Germ layers are produced during gastrulation and are the initial tissue layers of an embryo. Sometimes they are called embryonic tissue layers. They will develop into all the different tissues and structures present in an adult animal. 1  Ectoderm is the outermost layer of cells.  Mesoderm is the middle tissue layer.
During gastrulation, embryonic cells migrate through an opening within the embryo known as the blastocoele. As the gastrula forms, the remnants of the blastocoele shrink to eventually disappear completely. The opening into the gastrula is known as the blastopore. The inner cavity created by the infolding is known as the archenteron. The Way a cell turns to an embryo. Gastrulation is a phase early in the development of animal embryos, during which the morphology of the embryo is dramatically restructured by cell migration.
